that\'s the only lens i have an emmotional connection to, it took the first photos of my children minutes after they were born... one of the first things they saw was me with this lens.
Assertion: More reliant on digital corrections esp. at the wide end
Implications:
1. similar at the WIDE END, the F2 is trying harder than most RF lenses to correct in lens at the wide end, but it\'s so incredibly sharp at 28mm its hard to beat
2. MUCH lighter, best lens example here is probably the RF10-20, maybe some of that glass improvements on top of digital correction approach?
3. only marginal improvments AT THE WIDE END, if any: the biggest critique of the F2 is softness at 70mm, <5m focal distance, thats also where it has strongest LCA - but i haven\'t seen digital correction doing much for canon >50mm (e.g. 85 1.8)
4. narrower image circle - because the edge of the glass is getting corrected away anyway
5. worse real world IBIS, because of the narrower image circle
6. smaller filter diameter
Also: custom function button akin to the RF10-20
